Ga. Code § 33-9-26
Any person aggrieved by any rate charged, rating plan, rating system, or underwriting rule followed or adopted by an insurer or rating organization may request the insurer or rating organization to review the manner in which the rate, plan, system, or rule has been applied with respect to insurance afforded him. The request may be made by his authorized representative and shall be written. If the request is not granted within 30 days after it is made, the requestor may treat it as rejected. Any person aggrieved by the action of an insurer or rating organization in refusing the review requested or in failing or refusing to grant all or part of the relief requested may file a written complaint and request for hearing with the Commissioner, specifying the grounds relied upon. If the Commissioner has information concerning a similar complaint, he may deny the hearing. If he believes that probable cause for the complaint does not exist or that the complaint is not made in good faith, he shall deny the hearing. Otherwise, and if he finds that the complaint charges a violation of this chapter and that the complainant would be aggrieved if the violation is proven, he shall proceed as provided in Code Section 33-9-27.
